Package        : orthanc
Version        : 1.5.6+dfsg-1+deb10u1
CVE ID         : CVE-2023-33466
Debian Bug     : 1040597

A security vulnerability was identified in Orthanc, a DICOM server used for
medical imaging, whereby authenticated API users had the capability to overwrite
arbitrary files and, in certain configurations, execute unauthorized code.

This update addresses the issue by backporting a safeguard mechanism: the
RestApiWriteToFileSystemEnabled option is now included, and it is set to "true"
by default in the /etc/orthanc/orthanc.json configuration file. Should users
wish to revert to the previous behavior, they can manually set this option
to "true" themselves.

For Debian 10 buster, this problem has been fixed in version
1.5.6+dfsg-1+deb10u1.

We recommend that you upgrade your orthanc packages.

For the detailed security status of orthanc please refer to
its security tracker page at:
